What it adds

A regional tier between the lower and upper tiers that gathers regional misses before the long-haul fetch.

Where it helps

Audiences spread across many regions, or large objects where cross-region hops to one upper tier hurt.

The upside

Fewer long-distance fetches and stronger hit ratios for global traffic. Included with Enterprise.
